The anchor holes also serve as gas escaping passages during injection molding process. The mold has multiple poring gates to minimize the pressure gradients across the spiral wraps during the injection molding process. The metallic insert has also tubers sticking out from the tip of its spiral wraps. The tubers are firmly held by the mold in the injection molding process to prevent movement of the spiral wraps under the pressure from the injected plastic flow. The metallic inserts can be fully or partially coated by the plastic compound such that there is no metallic to metallic contact between the scroll members during operations. | 08-12-2010 |
20140140877 | SCROLL-TYPE VOLUME DISPLACEMENT APPARATUS WITH AN ORBITING THRUST BEARING - A scroll-type volume displacement apparatus with an orbiting thrust bearing. A scroll element of the first end plate in a fixed scroll engages with a scroll element of the second end plate in an orbiting scroll, the fixed scroll and the orbiting scroll are set in the main housing respectively. The purpose of the apparatus is to set the thrust ball bearing between the orbiting scroll and the base shell, which can orbit along the orbiting scroll, so as to balance the potential shake generated in the orbiting movement along the orbiting scroll through the multi-group thrust ball bearings. And, by the sealed contact between the orbiting scroll and the thrust ball bearing, the axial deviating force of the orbiting scroll can seal the pressure chamber to keep the slight contact of the front and behind face of the two scrolls which engages with each other. | 05-22-2014 |
